Rotate PDF
To rotate a PDF, turn every page at once or click individual thumbnails, check the previews and save. The rotation is written into the file, so it stays fixed when you email or print it — unlike rotating the view in a reader. Only a rotation flag changes, so quality is untouched. Nothing is uploaded.

How it works
Every page in a PDF carries a rotation value of 0, 90, 180 or 270 degrees that viewers apply when drawing it. Rotating adds your change to that existing value and normalises it back into range, then writes the updated page dictionary into a new file. The page content itself is untouched, so nothing is re-rendered and quality is unaffected.
This is different from rotating the view in a PDF reader, which usually forgets the change when you close the file. Here the rotation is stored in the document, so it opens correctly everywhere, including when printed.
The file is read into your browser's memory, changed there, and handed straight back to you. Nothing is uploaded, so there is no queue and no copy sitting on a server afterwards.
Tips and common mistakes
- Fix rotation before merging or sending a file. Nobody wants to tilt their head halfway through a document.
- Rotate only the pages that are wrong by clicking their thumbnails; the rotate-all button is for scans that are sideways throughout.
- Rotating the view in a PDF reader is usually forgotten when you close the file. Saving here writes the rotation into the document.
- A page scanned upside down needs a 180° turn — two quarter turns.
